Can't say that I've noticed Canada-bashing, per se. However, my advice would be to just let the idiots have their fun & don't feed into it.
Aside from talking a little funny (I JEST
), Canadians are some of the nicest people overall I've met. The plain truth of the situation is that Floridians would be hurting without the Canadian tourist dollar...and if that type of treatment became widespread, the idiots perpetrating it would probably be out of work & back in their parents' basements...if they've left by now.
